Reality itself runs on code. Invisible creatures called Promin keep the world functioning, each one a living program maintaining everything from gravity to memory. When these beings malfunction and corrupt into Bugmin, they cause everyday disasters: appliances failing, weather going haywire, people forgetting crucial moments. Most humans never notice the glitches. Yūto discovers the truth when he meets Wanda, a peculiar space dog with silver fur and impossible knowledge. Together they wield a device that lets them capture corrupted Bugmin before the damage spreads. Each creature they seal away requires strategy and timing, using Wanda's strange powers of acceleration, combustion, and creation. What starts as fixing minor inconveniences quickly spirals into something darker. The Bugmin infestations grow more frequent, more violent, spreading across continents. The two of them become humanity's only defense against a system collapse that could erase civilization itself. Yūto and Wanda represent hope against entropy: one ordinary kid and one impossible dog fighting to keep the world from unraveling, one corrupted creature at a time.
